This was recently discussed and now I cant find that. If you mean what I think you mean, there is one. Click on your dashboard and at the bottom of that list is what is called "Get my badge". Copy that and put it on your blog or web site. It is different than it used to be. It used to have a list of your last few articles, now it takes you to your profile. Actually I have never seen this new one before. I just tried it on one of my blogs and it is nice.

I just installed the 'get my badge' on my blog. I thought it would be a 'scrollable window' that showed the most recent articles that I have published, -but I guess that is 'a widget.'  The 'badge' is a direct link to the author's profile page (a link-rich enviroment that surely the 'bots will love!)

At any rate, it is still great to have the backlink from my blog to my profile/articles. It can get a few more iews of my exclusive works and perhaps generate additional traffic.
